Think about the question. In division, if you divide by 1, the number stays the same. If you divide by a larger number (like 10), the answer will get smaller. Therefore, you know to move the decimal to the left.

Here, there is one zero after the 1, so you move the decimal back one space. If it was divided by 100, the answer would be 0.165

Which is equivalent to tan θ?

Aloiza [94]

That which is equivalent to tanθ is A sinθ/cosθ

To answer the question, we need to know what tanθ is

<h3>What is tanθ?</h3>

Tanθ is a trigonometric identity which is the tangent of the angle .

Now, from the unit circle, with radius, r = 1, we have that tanθ = y/x.

Also, the sine of the angle θ is sinθ = x/1 = x

And also, the cosine of the angle θ is cosθ = y/1 = y

Since we have that

tanθ = y/x,
sinθ = x and
cosθ = y

Substituting the values of the variables y and x into tanθ, we have

tanθ = y/x

tanθ = sinθ/cosθ

So, that which is equivalent to tanθ is A sinθ/cosθ

amy is going to put 6 triangular tables together to make one large hexagon shaped table. what will be the area of the hexagon ta

tresset_1 [31]

Answer:

The area of the hexagonal table will be 27 square feet

Step-by-step explanation:

Given:

The height of the triangle = 3 feet

The base of the triangle = 3 feet

To Find:

The area of the hexagonal table = "

Solution:

<u>Step 1: Finding the area of the triangle</u>

The area of the triangle = $\frac{1}{2} \times base \times height$

On substituting the values

The area of the triangle is = $\frac{1}{2} \times 3 \times 3$

The area of the triangle = $\frac{9}{2}$ square feet

<u>Step 2 : Finding the area of the hexagonal table </u>

The area of the hexagonal table is = 6 X area of one triangle

The area of the hexagonal table = $6 \times \frac{9}{2}$

The area of the hexagonal table = $\frac{54}{2}$

The area of the hexagonal table = 27 square feet
